The primary risks include damaging straight-line winds and heavy rainfall capable of causing localized flash flooding. Central and western Iowa are expected to bear the brunt of the initial storm complex, with rainfall rates potentially exceeding 2 inches (50.8 mm) per hour in some areas. Flash flooding is a significant concern, especially where storms repeatedly pass over the same locations. Fairgoers at the Iowa State Fair should remain vigilant, as lightning and gusty winds could disrupt outdoor activities. While the tornado threat is low, the potential for severe weather during overnight hours increases the risk for unprepared residents.
